Single brake disc production die

Abstract

The invention discloses a single brake disc production die which comprises an upper die, pouring gates, brake disc templates, a lower die and a cold core partition plate. The upper end of the upper die and the lower end of the lower die are provided with the brake disc templates and the pouring gates correspondingly. Each pouring gate communicates with the corresponding brake disc template througha sprue. The cold core partition plate is arranged between the upper die and the lower die. The left end of the front side of the upper die and the right end of the rear side of the upper die are each provided with a clamping device. Each clamping device comprises a connection plate, wherein the connection plate is connected with the upper die, and the bottom end of the connection plate is provided with a rectangular box. According to the single brake disc production die, when the upper die and the lower die are used for fixing the brake disc templates, the upper die can drive the rectangularboxes to enter rectangular bases, springs spring clamping blocks into clamping grooves when the clamping blocks reach the positions of the clamping grooves, the rectangular boxes can be fixed in therectangular bases, stability between the upper die and the lower die is enhanced, the phenomenon that skewing occurs when the brake disc templates are fixed is avoided, and the forming quality of thebrake disc templates is improved.

Description

technical field [0001] The invention relates to the technical field of a production mold for a single-piece brake disc, in particular to a production mold for a single-piece brake disc. Background technique [0002] The brake disc of a motor vehicle is a very important part of the brake system of a car or other vehicles. The quality of the brake disc is directly related to the safety performance of the vehicle and is closely related to the safety of the driver. The traditional single-piece brake disc is cast in a single layer. The efficiency is low, and in the production process, the problem of brake disc shrinkage and loosening is prone to occur due to the existence of thermal junctions, resulting in a decrease in the quality of the brake disc and a low yield. For example, the invention with application number 201520398969.9 includes upper mold and lower mold The upper end of the upper mold and the lower end of the lower mold are respectively provided with a brake disc plat...

[0002] The brake disc of a motor vehicle is a very important part of the brake system of a car or other vehicles. The quality of the brake disc is directly related to the safety performance of the vehicle and is closely related to the safety of the driver. The traditional single-piece brake disc is cast in a single layer. The efficiency is low, and in the production process, the problem of brake disc shrinkage and loosening is prone to occur due to the existence of thermal junctions, resulting in a decrease in the quality of the brake disc and a low yield. For example, the invention with application number 201520398969.9 includes upper mold and lower mold The upper end of the upper mold and the lower end of the lower mold are respectively provided with a brake disc plate and a runner, and the runner communicates with the brake disc plate through the gate, and a cold core partition is arranged between the upper mold and the lower mold. The above-mentioned cold core partition is a cold core partition with adjustable thickness. Although the thickness of the cold core partition is used to adjust and control the position of the casting hot junction, it can completely avoid the shrinkage defect caused by the hot junction, but the upper mold and the The stability between the lower molds is poor, and the phenomenon of offset will occur when the brake disc plate is fixed, which will affect the forming quality of the brake disc plate
